To a who/)1 it "may concern.-

Be it known that we, EDWARD S. Massin and Jens HENRY 111;. wKINs,citizens of the United States, and residents of Quincy, in the county ofAdams and State of Illinois, have invented a new and Improved Circuit-Oontroller, of which the following is a speci iication.

Our invention is in nature a circuit closing timer, or controller,employed in the sparker circuit of explosive engines. I

The object had in view is to provide means of the character stated,adapted for general circuit closing uses, but specially intended 'l'oruse in sparker circuits as aforesaid.

The invention consists oi the peculiar construction and arrangement of parts shown by the :u companying drawing, the novel features beingpointed out in the appended claims.

in the drawing, Figure 1 is a plan or front view of my invention, andFig. 2 is a transverse vertical sectional view.

in the practice of our invention, we employ any suitable and properlyinsulated. case A, having its front closed by transparent material B,the same being secured on the case A, by a clamping plate 0 and setscrews D, will be understood. in. the case are ')rovided cams E,arranged on the end. of a shaft extended into the case indicated bydotted lines F. it will be understood that the shaft 1* is to haveproper operative connection with working parts of the engine.

G denotes a screw threaded tube extending into the case A, as shown byFig. 2. "he inner end cl the tube is constructed into a seat 11, adaptedfor support of a circular body or ball 1.

J, J denote j am-nuts arranged on the outer end. oi the screw threadedtube G, the nut J being more in the form of a cap adapted to close thetube opening, and is constructed with. an extended screw threaded shankK, forming with the nuts L, suitable binding post for connection of thecircuit wire M. it

will be understood that circuit is completed through the engine parts asusual.

in the tube G, we arrange a spring N, and the same is placed undertension holding the ball 1. yieldingly seated, by adj ustnwnt of the nutJ, as will be understood.

The construction of our invention will be understood from the abovedescription. In its use, the shaft F rotates the cams E will contact theunder portion of the ball I. During the contacting action, the ball isli'ltedv from its seat H, see F 2, and it is obvious that as thecontacting cam. E leaves the ball, the latter will be rotated toposition, presenting a new contacting surface for engagement with thefollowing cam, and it is further apparent, owing to the ball being freeas to its rotary movement, that through. "frictional engagement of thecams thm'ewith, its projecting surface, when seated, will be constantlychanged, and thus insuring con'lplete closure oi the sparker circuit, intimed arrangement, according to operative connection oi" the shaft Fwith moving parts of the engine.

We claim:

In a circuit controller and in conibination, a casing, a rotatable sha'lt extending into the casing, a rigid circuit contact device inv thecasing, said contact device being arranged on the rotatable shaltadapted to be rotated thereby, a tube arranged extending into thecasing, having inner and outer projecting ends, the tube being providedwith screwthread adjustment, an inner l'lange or seat on the inner endof said tube, a conductive ball device arranged in. the tube to beseated. on said flange and project beyond the tube, adapted to beengaged by the rigid rotatable contact device, adjusting nuts on theouter end. of the tube, a spring holding the ball device yieldinglyseated, and a binding post on. the outer end. of the adjustable tube.
